Although nonclostridial gas gangrene is not an unusual occurrence, relatively few cases including the distal lower extremity have been reported. Due to the serious nature of some of these infections, it is important for physicians to familiarize themselves with these nonclostridial crepitant infections, which are often confused with clostridial myonecrosis. Etiology, evaluation, and treatment is described by the authors. Also, a case study is presented.
